Create a footerview layout consisting of Button that you want to set as footer and then try

View footerView = ((LayoutInflater)ActivityContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.footer_layout, null, false);
ListView.addFooterView(footerView);

Footer_layout xml file

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:paddingTop="7dip"
    android:paddingBottom="7dip"
    android:orientation="horizontal"
    android:gravity="center">
    <LinearLayout 
        android:id="@+id/footer_layout" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:gravity="center"
        android:layout_gravity="center">

    <Button          
        android:id="@+id/footer_1" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
        android:layout_marginRight="5dip">
    </Button> 

</LinearLayout>
